Use ScriptRunner Behaviours to update value of parent custom field to subtask custom field

[Jeremy Johnson]

Goal:

I would like to have a behaviour on change script that updates the custom field of subtasks to the value that the parent updated to.  This is a free-text field entitled "Issue".

What I have tried:

Created a behaviour script for the Issue field, set to required (under Add Ons > Behaviours > [this project]).  So essentially this should run whenever that field is updated.

def subTasks = issue.getSubTaskObjects()
def issueValue = getFieldById(getFieldChanged())
subTasks.each {
it.getFieldByName("Issue").setFormValue(issueValue.getFormValue())
}

*this is the entirety of the code in the script for the Issue custom field on change listener

This produces no results.

When I check the atlassian logs, there are no errors shown, either.

Thanks in advance for any insight you can offer.

I'm not sure but I think you should use setCustomFieldValue.

it.setCustomFieldValue(issueValue.getFormValue())
